Title: Improvements in photographic toning processes
IPC: G03C5/46
Filed: 1933-02-24
Abstract: 401,548. Photographic toning processes. MAYER, and E., BENEDIK, N., (trading as MAYER & BENEDIK, Dr. E.), 111, Obere Donaustrasse, and NEUBER, F., 36, Bergsteigg, both in Vienna. Feb. 24, 1933, No. 5732. [Class 98 (ii).] A toning bath for photographic silver images consists of phosphates or arsenates and molybdates mixed in molecular or non-molecular proportions with the addition of acids, such as hydrochloric, hydrofluoric, thiocyanic or sulphuric acid. The tones produced vary from red through red-violet to blue according to the concentration of the bath and the duration of the treatment. A suitable bath for the process comprises phosphomolybdic acid, thiocyanic acid or potassium thiocyanate and hydrochloric acid. An after-treatment with alkali, e.g. ammonia, converts the red or blue tone into brown, and green tones maybe likewise produced by an after-treatment with sulphides or polysulphides e.g. sodium sulphide. The effect may be intensified by a further treatment in the original toning bath.

An electrical component is sealed in a recess in one face of a printed circuit ceramic plate, with its terminals projecting through holes passing from the recess to the opposite side of the plate and soldered to metallized areas around the holes, one of the areas being connected to an impedance element bonded to the surface of the plate. A transistor 58, Fig. 6, is sealed in a recess in plate 60, Figs. 5 and 7, and a disc capacitor 62 is mounted on, and with one electrode connected to a resistor 70 on, the top of plate 60, the other capacitor electrode being connected via ribbon 66 to lead 68, Fig. 8. Spring clip wiper 72 slides along both resistor 70 and a conductive strip, on the bottom of plate 60, which connects one terminal of the transistor to lead 88. A second transistor terminal is connected to lead 84, and the third is grounded to cover plate 59. Method of sealing component in recess.-Component 14, Fig. 1, may be sealed in cylindrical recess 12 by a metal cover plate 26, which may be a solder disc. The plate and the terminal 16 are soldered to metallized areas 20 and 22. A second embodiment (Fig. 2, not shown) employs a nickel ring placed in the recess, a flange at its upper end being soldered to the metallized areas 22 before insertion of the component, subsequent to which a nickel cover plate is soldered to the flange by concentric welding electrodes or by resistance heating. A further embodiment (Fig. 4, not shown) employs high-temperature solder between a ring contained in the recess and the metallized areas 22, and lowtemperature solder for sealing the top of the metal casing of the component to the ring, and for sealing the terminals. More than one component can be sealed in a recess in vacuum or nitrogen; a transistor so sealed may dispense with a metal container and encapsulating resin.

Class 103(6) A railway vehicle body structure 6, Fig. 1, is located with respect to the bogie frame 1 by a rigid hub 10 on the body engaging in a rigid annular body 11, on the bogie, with the interpositioning of an annular mass of elastomeric material 13, Fig. 2, the latter either having perforations 14 or reductions in thickness whereby longitudinal displacement of the body relative to the bogie is permitted against relatively great resilient constraint, transverse displacement of the body relative to the bogie is permitted against relatively smaller r constraint, due to the perforations 14 or reductions in thickness, and the body can rotate. relative to the bogie about a vertical axis. The body 11 is carried by transverse members 12 on the bogie, whilst the body 6 is pendulously supported on the bogie 1 by links 8, constructed in the manner described in Specification 714,296 and engaging between members 9 on the bogie and brackets 7 on the body 6. In another embodiment described with reference to Figs. 3, 5 and 8, the body structure members 22, Fig. 5, are connected, through horizontal transverse trunnions 25 and elastomeric masses 26, with a sub frame 21 pendulously supported from the bogie side frames 15 by links 29 described in Specification 714,296 and connected between brackets 30 on the bogie and abutments 32 on hollow brackets 28 of the sub frame 21. Axle boxes 16 are connected to the side frames 15 by links 17 and torsion joints 18 of the kind described in Specification 652,266. Referring to Figs. 3 and 8, hollow members 38 on the sub frames 21 house inner members 37 rigidly connected by crank arms or webs 36 to inner members 35 housed within outer hollow members 33 fixed to transverse members 34 between the side frames 15. Between the members 33, 35 and 37, 38 are disposed elastomeric masses 39. These joints are also as described in Specification 652,266. For longitudinal displacements of the sub frame relative to the bogie the masses 39 are compressed and no torque is applied to the joints. However, for transverse displacement of the sub frame relative to the bogie, torques are applied to the joints and rolling of the masses 39 in the spaces between the inner and outer members occurs so that there will be smaller resilient constraint in this direction. The torsion joints 33, 35, 36, 37, 38 at each end of the sub frame 21 also permit rotation of the body 22 relative to the bogie about a vertical axis.
